• The Nike Racing shoelace is lightweight with notches and just a little stretch that allows for a secure fit that stays tied in all conditions

Traction & Durability:

• Completely new plate using computationally designed hexagons delivers stiffness in key areas to help you fly off the starting line and maintain speed throughout the race
• Data from hundreds of runners helped inform the outsole

Additional Details:

• Designed for 60 to 400 meter events
